Answer:
<h3>73220±566.72</h3>
Step-by-step explanation:
The formula for calculating the confidence interval is expressed as;
CI = xbar ± z*s/√n
xbar is the sample mean = $73,220
z is the z score at 99% CI = 2.576
s is the standard deviation = $4400
n is the sample size = 400
Substitute the given values into the formula;
CI = 73,220 ± 2.576*4400/√400
CI = 73,220 ± 2.576*4400/20
CI = 73,220± (2.576*220)
CI = 73220±566.72
Hence a 99% confidence interval for μ is 73220±566.72
Answer:
The answer is three
Step-by-step explanation:
The formula to find the area is the width times the length. The area of the big rectangle is three times more than the smaller rectangle.
It is either 400 or negative 400 because if you devide 12 by .03 it is 400
Answer:
yes but no a statistical question is determined by requiring multiple data
Step-by-step explanation:
Answer:
g(x) = -|x| + 1
Step-by-step explanation:
Let g(x) be the transformation function
-|x| reflects f(x) across the x-axis. Add 1 to move the result up one unit
So, g(x) = -|x| + 1
